Olive oil... or just mayonnaise. You could go out and spend $8 on a 'hot oil treatment' or you could warm 1/4 cup of olive oil in your microwave (like 10 seconds) and glop it on, wrap your hair in saran wrap, and then a towel and watch a movie... wash your hair as usual, but don't try too hard to get the oil out, especially of the ends.
Alternately, you could buy shampoo and conditioner specifically for chemically-treated hair. It helps to push some of the water off your hair before conditioning, so it doesn't float over the water and actually gets to your hair... it also helps to shampoo and condition right away in the shower, so you can leave the conditioner on while you do everything else, then rinse just before you get out.
Use slightly cooler water, too. Hot water strips natural oils from your hair, which makes what the chemicals did a whole lot worse.
